Welcome to TFP

  1. TP Code (Low Water Pressure):
    • The TP code typically indicates low water pressure in the heat pump.
    • Here are some steps to address this issue:
      • Check the Pool Pump: Ensure that your pool pump is receiving enough water and sending it to the heat pump.
      • Clean the Filter: Make sure the filter is clean.
      • Bypass Valve: Verify that the bypass valve is closed.
      • For variable-speed pool pumps, consider increasing the pump speed slightly.
I would have guessed it needed more toilet paper.
